About ONE PLANET
ONE PLANET is a 2023 Sunreef 77 sailing catamaran and one of the first fully electric yachts of her size available for charter. Solar panels integrated into her hull and superstructure feed a 285 kWh battery bank driving two 120 kW electric motors, so she cruises and lies at anchor with zero emissions, no engine noise and no vibration – running on little more than wind and sunlight.
Up to eight guests stay in four en-suite cabins: a master cabin with king bed and three queen cabins. Life aboard spreads across a shaded aft deck, a large foredeck lounge and a flybridge made for sunset cocktails and dinners, with indoor and outdoor cinema, Starlink Wi-Fi and a cockpit misting system for natural cooling. A crew of six, including a Michelin-trained chef, sails her in the Western Mediterranean in summer and the Caribbean in winter, with Seabobs, an e-foil, wing foils and a 110 HP jet tender for play.
